Abstract
A system for treating a vascular condition includes a stent including hydroxyapatite fibers interwoven to define a stent lumen. Another aspect of the invention is a method of manufacturing a stent by forming hydroxyapatite fibers and biodegradable polymeric fibers, and interweaving the fibers to form a stent wall. The hydroxyapatite fibers can be formed by a sol-gel process, followed by spinning of the gel to form the hydroxyapatite fibers.
Claims10
A stent consisting of:
- hydroxyapatite fibers, the hydroxyapatite fibers consisting of biodegradable polymer filaments coaxially aligned in a mesh along the length of the hydroxyapatite fibers and hydroxyapatite particles bound within the mesh;
- and
- biodegradable polymeric fibers;
- wherein the hydroxyapatite fibers and biodegradable polymeric fibers are interwoven to define a stent lumen.
